摘要

An apparatus for the application of adhesivecoated slips to a moving web or t o workpieces beingconveyed, and preferably to the drawn up and still openbottoms of bags, consists of pairs of feed rolls for a webof material and means for perforating and tearing off, ormeans for detaching, the slips from the web of material andof a transfer folding gripper cylinder for receiving andsubsequent transfer of the slips or pieces of tube. Inorder to be able to apply additional slips between anapplying folding gripper cylinder for the application of theslips and the transfer folding cylinder there is anintermediate cylinder, which with the applying foldingcylinder defines a roll nip, into which slips run, which aretorn off or otherwise detached along lines of perforationsfrom a second web of material are inserted, and whichtransfers the slips or pieces of tube which are torn off orotherwise detached from the first and the second web ofmaterial in an at least partly overlapping condition to theweb or, respectively, workpieces passing through the device.
